Wave fields, both measured and forecast during the very severe cyclone Phailin, are discussed in this communication. Waves having maximum height of 13.54 m were recorded at Gopalpur, the landfall point of the cyclone. The forecast and observed significant wave heights matched well at Gopalpur with correlation coefficient of 0.98, RMS e rror of 0.35 m and scatter index of 14%. Forecasts were also validated in the open ocean and found to be reliable (scatter index < 15%). The study also revealed the presence of Southern Ocean swells with a peak period of 20-22 sec hitting Gopalpur coast along with the cyclone-generated waves.Keywords

Ocean-met observations from INCOIS real-time automatic weather station on-board a ship RV Kaustubh served as strong ground truth for satellite- and modelderived forecasts during the very severe cyclonic storm Hudhud, which made a landfall at Visakhapatnam, India. The ship recorded maximum wind speed of 204 km/h (with a minimum central pressure of 945 hPa), which is the highest (lowest) ever instrumentally recorded value at a location on the Indian coastline during any cyclone. Though the global model forecasts of wind fields have shown good agreement inland, they failed in representing the reality along the coasts. Variation in wind energy from ocean towards inland suggests that it is attenuated exponentially inland (the maximum wind power density had reduced by 93,406 W/m2 at Anakapalle (~25 km) compared to the ocean, and by 7022 W/m2 at Chintapalle (~100 km inland) compared to Anakapalle). The present study reinforces the significance of having realtime near-shore ocean-met observations, and their operational usage for evaluation (assimilation) of (into) ocean-met forecast models in realtime.Keywords

The Indian Tsunami Early Warning System (ITEWS) was established at the Indian National Centre for Ocean Information Services, Hyderabad in October 2007 following the devastating tsunami on 26 December 2004. The Intergovernmental Oceanographic Commission of United Nations Educational, Scientific and Cultural Organization (IOC/UNESCO) coordinated with the National Tsunami Warning Centers in the Indian Ocean region and promoted the establishment of a well-knit tsunami early warning system called Indian Ocean Tsunami Warning and Mitigation System (IOTWMS) so that all countries on the Indian Ocean can get benefitted. The end-to-end capabilities of this warning system have been well-proven during the tsunamigenic earthquakes that occurred since September 2007. The capability of the system is examined, with special reference to Indian Tsunami Early Warning System (ITEWS), to ascertain the readiness of the Indian Ocean region to face a major tsunami.Keywords
